Mt. Fuji trek doubts

I am planning to trek Mt Fuji from Osaka over the next weekend ( evening 9PM from Umeda and be back by Sunday night for work on Monday ). First of all is this even possible ?
Putting JR osaka to Yoshida 5th station in google maps give all sort of answers for a departure after 830, with arrival on Saturday after 4PM.

I read that restricted hours are from 2pm to 3am or you have to book a hut. Yoshida trail huts at top have no information online. What about those who start it at 1pm with no hut booked ? As they would be trekking back in the dark.

How to do this trek ? Is it possible ?

P.s. I have trekked mountains with more altitude than this and have hiked in Japan regularly.
